Wiltshire's very own test and trace service will go live tomorrow (November 18), the council has announced.
In a media briefing, Kate Blackburn, director of public health for Wiltshire, said the local service will support the national effort by contacting local positive cases the national system is unable to reach.
Ms Blackburn said: "The local service will support the national NHS Test and Trace service so we'll step in should the national team be unable to reach the person in Wiltshire who's tested positive for Covid-19.
"At the moment, about 75 per cent of people get followed up by the national system in Wiltshire. The Chief Medical Officer has always said that really it needs to be 80 per cent and over to make a real difference so we're really pleased to be able to now have this enhancement locally to be able to bring that percentage up."
People who contract Covid-19 will initially receive a text message followed by a call.
The number Wiltshire Council officers will be calling from is 0300 4560100.
Anyone who receives a call from this number is urged not to ignore it, with the council asking people to save it so they immediately recognise it.
Thirteen public health staff will be involved with the local test and trace to start with.
However, that number will be kept under review as cases rise, Ms Blackburn said.
Members of the public are also being reminded that failing to self-isolate can result in a fine of up to £10,000.
